THE PROPERTIES OF THE ANDREEV REFLECTION IN FERROMAGNET-INSULATOR-d WAVE SUPERCONDUCTOR JUNCTION
铁磁-绝缘层-d波超导结中的Andreev反射特性

Taking into account the exchange interaction in the ferromagnet and the interface scattering effect, within Blonder-Tinkham-Klapwijk scattering formalism, we have calculated the quasiparticle transport coefficients and the tunneling spectrum in the ferromagnet-insulator-d wave superconductor junction. It is found that the ferromagnetic exchange interaction can suppress the Andreev reflection, and consequently the Andreev reflected quasiparticle shows an evanescent-wave behavior depending on the injection angle of the quasiparticle. The tunneling spectrum exhibits some novel features.
